i'm using this:

http://www.meguiars.com.my/product/517

but my car is only 5 months old. so its difficult to tell if its effective or not

The clear coat has been gone and base paint already exposed, nothing you can do, or else repaint your car..

Because your base paint has been exposed, it can't be done...my old wira car happened before... nothing you can do with polish or wax

heres the thing with cost, for TW, its cheap, however i tend to spray a lot as it wasn't that effective.
the good thing about it is that it is rather... gentle to the wheels. so far never had damage on tires/wheels etc despite over spraying a ton.

however if sonax is very effective, and overspraying may cause damage? (abbrasive, solvent?) you could probably use very little and get the same/better results.

TW is between rm23-30 for a spray bottle of 768ml, much cheaper, but a bottle can only last maybe... 20-40 wheels or so...

that said, brake dust isn't that huge of a concern now since i'm on expensive brake pads that produce absolutely minimum dust no matter how hard i brake (160-170+ down to a full stop LOL)

Sonax Malaysia has an fb up under that name. Might be a better idea if you ask them there. I see they have some of their products in Caltex Penang....but didn't mention which Caltex and what products....hehehe....

Rebelious mood.....hehehe.....
Any idea what could have caused that? Can't really judge from the picture. Looks like either calcium deposit (those whitish thingy that drips down from basement parking lots) or very oxidized/failed clear coat. What car? Age?

For a 20 years old paint, it could already be the clear coat failing. But then, from the way you describe it, it *could* also be some sort of deposits...rain picking up paint/plaster/dirt, etc then deposit them (dripping from the awning) onto the surface of the paint then dried up. Might be able to save it if the clear coat underneath is still ok. Does it feel sandy-like and protruding/sticking on the surface? Do you see anything resemblance to peeling plastic wrapper (clear coat peeling off)?

Bad news guys, Sonax only open until 1pm on Saturdays.
Why don't you guys do a group buy, get the 5L one and share it out. What you guys should be looking for is the Sonax Xtreme Wheel Cleaner Full Effect and I think they retail here for around RM80 for the 500ml spray bottle. I can try to get info on the availability and price for the 5L container....later after lunch la ya.....

The SS18 is the main dealer/distributor. Much like Hypercoat in USJ1.

The plus side of this wheel cleaner (from my limited experience...errr...which is after using about half of the 5L container ) is that it's able to 'melt' those difficult to remove brake dust whilst not damaging the paintwork/coating, unlike some other caustic wheel cleaners (eg. Megs Wheel Brightener - more effective and works quicker) which requires more care and getting use to.

mini-guide on watermarked/blurry windscreens courtesy from krismas and other forumers who provided tip on v1 thread previously:

oh prior to the singapore trip with family, the 4 to 5 hours of detailing work on the nissan sentra totally paid off:
rained all the way back from singapore to KL Malaysia, and the windscreen/windows /side mirrors was repelling water splendidly!
barely need to turn on the wiper at all as the wind from the car's speed is enough to repel most, if not all of the rain.

method

result = water hates your windscreen now 
oh and rain x water beading result is quite pretty too lolz
sorry no pics since was speeding and family's safety is a priority (yes i know that isn't saying much since i was speeding  )

btw thread pinned
